IMRovEMnN'r 1N HEAT-RADIATOR.

Tha Schodule referred ton; 'these Letters Patent and making partzoi thesama. i

Be it known that I, WrLLiAM B. OHOA'rE, of Galt, Canada lVcst, haveinvented a uew'aud useful linprovement in Heat-Radiators; and I dohereby declare that the following is atull, clear, and exact descriptionthereof, which will enable thosev skilled in the art to make i-nd usethe saune, reference being had to the accoinf penying drawings, tbrniingpart of this specification. This invention' relates to n new and usefulin'ipro\'cnient in radiators for heat, to beattached to stoves, and usedin all situations where they may serve the purposes for which they areintended. l

And the invention consists in the combina-tion, with a radiator ofserpentine thun, ci' the method of placing the lianges ou theend-plates, and in depressing the iiue. of the radiator after the curvesor turns, 'so as to forni a series of diving-hues.

The drawing, Figure l, represents a vertical seetional -elevation of myradiator attached to a stove, and connected with a, stove-pipe, thestove and the stovepipe being shown in red color in the drawing.

'Similar letters of reference indicate correspondingr pants.

A represent-s the radiator, of serpentine shape, o1' formed into esuccession of curves or turns, as seen in the dra-wing.

B represents stays, which are attached to each ofthe horizontal sectionsof the serpentine tine or radiator, for supporting it and keeping it inplace.

The 'end-pieces G (l ol" this radiator may be mede ot' The radiatoritselt` is runde of sheet-iron.

The heated products of combustion, in passing up through this radiator,willimpinge against the upper surface, and the heated current willrepeatedly change its position during its progress, thereby exposingevery portion of the rnoving current to the heat-radiating sur fece. l

This radiator isaJ attened tube, as seen in the top view, Figure 2,audit will be seen that, with the few curves .and turns shownin thisexample 'of my inven.`

tion, a very extensive heat-rediating-surfce is presented to the nir.

The importance of this feature in al heat-radiator becomes apparent'when we consider that nir will not heat nir, and that to heet kor warm'the nir in a. room, every particle of air must be brought in contactwith ,al heated surface.

A current is thus formed, setting-towards the radiator. The air, as itis heated by Contact with heated metal, becomes iareliedand illesupward, while the colder air rushes in to take its place. .y

` The 'heated products of combustion passing into this radiator areforced to pertwith their contained caloric,"

ot' the plates, are `not continuous or unbroken, but that Y a portion(that portion which forms theouter orlarge curve) is set inward on theplat-e, andthat the. part-'43T the flange f, which forms the inner 'and'smell curve, and also the stm-ight portion of the tube, encloses theserpentine sides ofthe tube.

By this method of formation the corrugated sides are v much more easilymanaged in putting the radiator together, and much more easily kept inplace, as they are not so much effected by the expansion andcontraction.

byl heat.

The end-plates of the radiatorE can bemost rel ily made of enst-iron,and they are held'together (with the serpentine or corrugated sidesbetween them) by transverse rods with screw-nuts, which pass throughholes g, as seen in the drawing.

A It will be noticed that the outer curves of the serpentine tube aredepressed, so that each certain extent) a diving-flue.

The tendency of hen-t to seek the highest portion oi' avhorizontal tubewill produce a cha-nge in the current at every turn, and vthat change is.1nade more perfect,

and all central current more completely destroyed, by fcompelling thecurrent to descend'atter'every turn.

Having thusldescribed Iny invention,

' What I claim as new, and desire to secure by Letters Patellis, is- Yl. In combination' witha radiator of serpentine forni, the method ofplacing the flanges al and f on theeud plates, substantially as shownand-described.

2. Depressing the line of the radiator after the curves or turns, so asto form n series of diving-fines, substantially as and for the purposeset forth. v
